Curving glide path was ‘invented’ by Jeffrey Quill RANVR for carrier landings.

Subject: Re: [Aus-soaring] Loss of control accidents The Americans were regularly killing pilots landing on aircraft carriers until they adopted the British system of a continually curving final glide path. I have been told that the idea is sometimes used in NZ when landing on short or difficult strips. Perhaps others can elucidate.

The Aircraft Owners and Pilots Association (AOPA) is working with UND’s aviation department to test a circular landing pattern used by the military, an operational modi- fi cation of cials think can reduce the stall-spin problems occurring in the rectangular landing patterns taught to and used by virtually all GA pilots. George Perry, senior vice president of the AOPA Air Safety Institute (ASI), says the circular pattern, which he used as a U.S. Navy pilot, is “easier, more stabilized and allows the pilot to more easily identify the precursors of an impending stall” than the tradi- tional rectangular pattern. “The only pilots who do the crazy box pattern are the GA pilots,” he says. The study, which started in June, will “get hard data to show whether it is a better way to fly a pattern based on workload and standardization,” says Perry. A preliminary study with 13 pilots flying a wide variety of air- craft (Cessna 140 to Cessna Citation) at AOPA’s headquarters in Frederick, Maryland, showed that the pattern “works for a full spectrum of GA air- craft,” says Perry. If the results of the UND study are positive, Perry says, ASI will work with the FAA to introduce the concept to pi- lots in training and testing materials. “My goal is that in 3-5 years, the square pattern will [have gone] the way of the Dodo bird.” Mike Borgelt Instruments - design & manufacture of quality soaring instrumentation since 1978 www.borgeltinstruments.com tel: 07 4635 5784 overseas: int+61-7-4635 5784 mob: 042835 5784 : int+61-42835 5784 P O Box 4607, Toowoomba East, QLD 4350, Australia _______________________________________________ Aus-soaring mailing list [email protected] http://lists.base64.com.au/listinfo/aus-soaring -------------------------------------------------------------------------------- _______________________________________________ Aus-soaring mailing list [email protected] http://lists.base64.com.au/listinfo/aus-soaring -------------------------------------------------------------------------------- _______________________________________________ Aus-soaring mailing list [email protected] http://lists.base64.com.au/listinfo/aus-soaring
